[osg-users] DDS Textures

[David Heitbrink]

I have two separate issues with DDS textures. First and the most annoying is after moving from  OSG-3.2.x to OSG-3.4.0 my grayscale textures now show up red. I did not change the source textures or models between versions.

I have another problem with mip mapped dds textures. I have a number of textures that have mip maps, stepping through the code after they are loaded, it looks like OSG has the texture setup to use the mip maps. What I am seeing it is clearly not using the mip maps. I modified a texture to alternate the color on every level. I got the largest texture the entire time. I also used a shader to turn the model solid red, if it had only 1 texture level, and I got a red model. I suspect this might be more of a driver/video card issue (Quadro K5000).
